Edwards Signaling 5531MHV Series Adaptatone Millennium is a high volume, 30 watt heavy-duty industrial signaling device capable of producing volume-controlled, high-decibel tones. Four tones can be activated from field-wired, normally open contacts, or a 24VDC or 120VAC external voltage source such as the output of a PLC. Normally open contacts can be obtained from the Cat. No. 5538-4 and/or Cat. No. 5538-4R Adaptatone Signal Actuators. The unit uses a microprocessor circuit to create 55 distinctive tones, selected by setting miniature dip switches within the unit. The tones programmed operate on a pyramid-type priority system in which a switch with a programmed tone takes priority over all switches that follow it. Designed for industrial applications including emergency warning systems, plant evacuation and security intrusion alarms, process monitoring, shift start-and-dismissal horns, and paging signals. The 5531M is designed for either 1/2" (13mm) conduit or surface mounting.
